About myself

I am an experienced researcher of next-generation urban infrastructure systems in a changing climate. My particular interests lie in geospatial analytics, the water-energy-climate nexus, sustainable, extreme temperature events, urban planning and the sustainable transition of current infrastructure systems. I am an Associate Scientist at ZHAW at the School of Architecture, Design and Civil Engineering. My background is highly interdisciplinary and my research is bridging the fields of geospatial analytics, urban planning, economics, environmental sciences and engineering. My research is motivated by the challenge to transition our urban built urban environment and infrastructure systems into a sustainable future and to adapt and mitigate climate change. Before moving to ZHAW, I was a researcher at the Urban Energy Systems Laboratory at Empa (ETH-Domain). Before that, I was part of the Infrastructure Transition Research Consortium and was leading the development of a national energy demand simulation model for an integrated system-of-systems model (called NISMOD2) at the Environmental Change Institute at the University of Oxford. I received a PhD at the Swiss Federal Institute of Aquatic Science and Technology (eawag) and the Swiss Federal Institute of Technology (ETH). In my PhD thesis, I analysed the potential for a sustainability transition of decentralised wastewater treatment systems and the role of data-driven technologies for which I received one of the prestigious ETH medals. Prior to this, I was awarded an MSc in Geography with a specialization in Geographical Information Systems at the University of Zürich (UZH).
